The Reception block consists of:
The “Filter”. The input data are filtered depending on the selected baud rate. The block extracts the bit
synchronization clock. When an external bit synchronization clock is used, the filter is bypassed.
The “Start Detection” block. This block detects a programmable start sequence and therefore synchronizes at
the message start. The interface ignores incoming messages until the start sequence is detected. This block
can be bypassed or an external message synchronization signal can be used (match in Figure 14-1).
The “PCM Decoder” which decodes the 3 main types of PCM waveforms ( i.e. NRZ, Bi-Phase, Miller). This
block can be bypassed.
The “Shift Register” and the FIFO, that do the serial to parallel conversion and memorize the input data.
The Transmission block consists of:
The FIFO and the “Shift Register” which store the data and do the parallel to serial conversion.
The “Encoder” which encodes the serial data into the chosen PCM type. This block can be bypassed.
The Prescaler generates the clock signals needed for the reception and transmission depending on the selected
baud rate and PCM code type.
